Ultrafast optical circuit switching for data centers using integrated soliton microcombs
Arslan Sajid Raja, Sophie Lange, Maxim Karpov +13
Networks inside current data centers comprise a hierarchy of power-hungry electronic packet switches interconnected via optical fibers and transceivers. As the scaling of such elec…
Monolithic piezoelectric control of soliton microcombs
Junqiu Liu, Hao Tian, Erwan Lucas +9
High-speed laser frequency actuation is critical in all applications employing lasers and frequency combs, and is prerequisite for phase locking, frequency stabilization and stabil…
Packaged photonic chip-based soliton microcomb using an ultralow-noise laser
Arslan S. Raja, Junqiu Liu, Nicolas Volet +7
Photonic chip-based soliton microcombs have shown rapid progress and have already been used in many system-level applications, including coherent communications, astrophysical spec…
Double inverse nanotapers for efficient light coupling to integrated photonic devices
Junqiu Liu, Arslan S. Raja, Martin H. P. Pfeiffer +5
Efficient light coupling into integrated photonic devices is of key importance to a wide variety of applications. "Inverse nanotapers" are widely used, in which the waveguide width…
Probing the loss origins of ultra-smooth integrated photonic waveguides
Martin H. P. Pfeiffer, Junqiu Liu, Arslan S. Raja +3
On-chip optical waveguides with low propagation losses and precisely engineered group velocity dispersion (GVD) are important to nonlinear photonic devices such as soliton microcom…
